AUSTIN O. EVANS, OF SPRINGFIELD, OHIO.

CORN-PLANTER.

SPECIFICATION forming part of Letters Patent No. 241,129, dated May 10, 1881.

Application filed November 15, 1880. (Model.)

To all whom it may concern:

Be it known that I, AUSTIN G. EVANS, of the city of Springtield,in the county of Clarke and State ot' Ohio, have invented' a new and useful Improvement in Corn Planters, ot' which the followingis a specification.

My invention relates to a wheeled planter; and it consists in certain improvements in the dropping devices bothl in the seed-disk and the devices connected therewith, whereby the dropping is more certain and greater regularity ot' discharge is effected, as the locking of the operative parts at any point by a partial stroke ot` the lever is entirely prevented, as will be hereinafter more fully set t'orth and specifically claimed.

Figure l is a plan view of the seed-disk and its connections, Vthe seed-box being removed. Fig. 2 is a longitudinal elevation ofthe same, a portion of the base of the seed-box being shown. Fig. 3 is an end view ot' the device as shown in Fig. 1. Fig. 4, Sheet 2, is aside elevation ot' the rear portion of a planter having my improved marker attachment connected therewith; Fig. 5, the coupling enlarged.

In the views, A is the seed plate or disk,

l whichis provided, as usual,with seed-cells, and

from its edge extend the long teeth a a. It lies over an open oblong frame, B, having journals a" extending centrally from its ends, upon which it is pivoted in boxes a/ on the ends of the actuating slide-lever C. As the latter is reciprocated each sidebar of frame B alternately rises and falls, as seen in the dotted lilies, Fig. 3. This oscillatorymovement is caused during the passage of the frame under the disk by the long raised lugs b and b2 seen on each side bar ot' the frame. The front ends of the lugs are vertical, to push against the face ot' tooth a ot' the disk. The rear ends slope ot't', so as to allow them to readily pass under the tooth ofthe disk, and thereby depress the side bar opposite to thel driving side (see Fig. l, the top bar of which corresponds with the depressed bar seen on the right in Fig. 3) as the frame B is reciprocated back and forth.

By reference to Fig. 1 it will be noticed that when the frame is pushed to the right by the action of the slide-lever the lower long lug, b', strikes the face of tooth a', rotating the disk to the left, and that the tooth a2 slides over the lug b2 on the upper or depressed bar of the frame, the right or rear end being beveled or sloped oit' for that purpose. As soon as the tooth a2 has arrived at the lett end ot' the lug (which is at right angles to the plane of the bar) the latter rises, bringing the lug up between tooth a? and the next on the right ofthe disk, and so on in the order ot rotation. At the point where lug b2 on the upper frame-bar, c, rises. between (1? and the next. tooth to the right, frame B will have reached the end of the stroke, and this side now becomes the driving side, lug b2 on it pushing against the face of tooth a? as the slidelever is thrown to the left, and tooth a3 now slides over the lug b on the lower frame-bar, c', (the rear or sloping` end of which is at the 1eft,) in precisely the same manner. It will be seen by reference to this ure and to Figs. 2 and 3 that during any partial stroke ot the lever one ot' the lugs b or b2 must be under a tooth ot1 the disk, and thatit is impossible to lock the parts under any circumstances, and also that the drop will not take place till the lever arrives at the end ot' a full stroke.

A stop of triangular shape is seen in Fig. 1 at the left upper and right lower corner ot' the frame B. These stops d are about the saine height ot' the lugs b--i. e., about equal to the thickness ot the disk A. They serve to catch the rear otl the 'driven tooth at the end ot the stroke and prevent the plate from rotating too far. The point ot' each tooth of the disk is beveled to correspond with the inner angle of the stop, so as to allow them to pass as the disk receives its next impulse. rIhe oscillatory motions of frame B are automatic, certain, and positive, and as the power is applied at the extreme verge of the disk, against the face of its extended tooth a on each side alternately, the device is easily operated and is very accurate in its work. In Figs. 2 and 3 the connection ot' slide-lever C with the oscillating frame B above and the tubular seed-valve is seen. In the latter gure the connection with the valve is shown in dotted lines.

D is the rear ot' a planter-frame; d', the rear bar ot' the same. On the top ot' this bar, at the middle of the same, is bolted a swiveled coupling, E, consisting ot' a fork, e, and a tubular sleeve, e', having dan ges on each side, by which IOO it is bolted to the frame-bar d in line with the planter-frame. The fork e has a cylindrical shank and turns easily in the sleeve. The pole or bar fot the marker has its inner end pivoted in the fork by a pin, so that it can be placed in any position, as shown in the line and angular positions and in the positions shown in the dotted lines in Fig. 4. Instead of the usual rigid attachment, which allows the marker to assume only its operative positions on either side, this coupling allows the marker to be thrown in any desired direction, and also permits of its being Folded upon the frame ofthe machine.

I am aware that swiveled couplings as applied to other purposes are not new.

I claim as my improvement- 1. In a rotary seed-droppingdevice for planters, the elongated teeth a ot' the seed-disk A,

having their ends inclined or beveled on their.

face sides near the point for the purpose of facilitating their disengagement from the triangular stops don the oscillating frame B as the device is operated.

2. In a rotary seed-dropping device for planters, an oblong frame pivoted in bearings on the end of the slide-lever, in line therewith, said frame being interposed between the seeddisk and the discharging-valve and adapted to have an oscillating movement, whereby its lugs d are made to engage with the teeth of the` seed-disk on opposite sides alternately, as and for the purpose hereinbefore set forth.

3. In a rotaryseed-dropping device for planters, a slide-lever having bearings or boxes on the ends of the same, in line therewith, for the pivot ends of an oscillating frame `iournaled therein, as and for the purpose hereinbefore set forth.

4. In a rotary seed-dropping device, the combination, with a seed-disk constructed as described, ot' an oblong oscillating frame provided with raised lugs adapted by the rising and falling movements of the side bars of said frame, on either side alternately, to engage the teeth ofthe seed-disk and rotate the same, as hereinbefore specified, at each thrust of the slide-lever.

5. In a rotary seed-droppin g device forplanters, an oblong oscillating frame pivoted centrally in line of the slide-lever in bearings thereon, having a long elevated lug on the top of the same near the inside edge of each side bar, with a vertical front end, and its rear end sloped oft', so as to allow its front end to engage the face ofthe teeth ofthe seed-disk when elevated, by the motion ol the frame, to the same plane, and to allow it to pass under the teeth of said disk when depressed below it on either side alternately as the device is operated.

6. In a rotary seed-dropping device forplanters, the combination of a seed-disk, A, having elongated bevel-ended teeth af, an oblong oscillating frame, B, having the long drivinglugs b and b2 and the triangular stops I cast thereon, pivoted in bearings on the slide-lever C beneath said disk, and adapted to operate the same from each side alternately by the actuation of said lever, as and for the purpose set forth.
